Tue, 12 Aug 2008 00:24:42 +0000 | Aaron Wishnick | General cleanup and fixed a buffer overrun bug. It may be necessary to normalize filter gain differently or something. gsoc2008_audio_resampling |
Thu, 10 Jul 2008 07:02:18 +0000 | Aaron Wishnick | Made a very significant optimization to the FIR filter which I believe I can take a little further. Right now the FIR filter size is 768 and I get some free() bugs, so this is something I need to debug. gsoc2008_audio_resampling |
Wed, 02 Jul 2008 08:04:50 +0000 | Aaron Wishnick | The windowed sinc filter generation code seems to be working fine. The FIR filtering code is also now working reasonably well. Occasionally the FIR filter will pop, but setting the normalization factor lower seems to help this. I suspect the problem is in the fixed point multiply/add. I also have a hunch the zero stuffing/sample discarding code is not correct, and I'll look at that soon to get it sorted out. gsoc2008_audio_resampling |
